Well, I'm going for the PRO_version asap. So by the end of next week I'm hoping I can pretty much use any PIC (within the confines of the PICkit1) I like.Code:I was just wondering so we could make lessons to match your hardware...
If you let me know what you think I'll need I can order it in.
I really appreciate what you're doing by the way.

I think the serial parts we talked about will be good for now. That will give a way to debug and learn how to communicate with another device.If you let me know what you think I'll need I can order it in.
...Do you have a solder-less breadboard? and some miscellaneous LEDs and resistors? ...
What comes around goes around...I really appreciate what you're doing by the way.

No but I saw one in Maplins the other day, I'll pick one up.Do you have a solder-less breadboard?
Yes I do, hey I'm LEDave...and some miscellaneous LEDs and resistors? ...

Might I suggest a LCD display?
Getting an LCD up and running might be a good experiment, and it's also a handy tool for debugging code later.

I'm game, don't forget I couldn't turn an LED on a few weeks ago though!Getting an LCD up and running might be a good experiment, and it's also a handy tool for debugging code later.

Is there a surplus store over there like this?

There's RS
They have these (and I've got an account).

Or Maplins again:

The RS range seems far superior.

Sure, most of us couldn't flash an LED when we started.
But Mackrackit is doing a nice job of getting you up to speed, and a parallel LCD display isn't that hard to set up.
You'll need to set up 4 pins on your PIC, all on one port for your LCD data lines, and 2 more pins for Enable and Register Select
You'll need to make sure that those 6 pins are setup as digital outputs and any other stuff that shares those pins (ADC, comparators, etc) are disabled.
Once the pins are set correctly then you'll add a few DEFINE's to your program to tell the PIC where to find your LCD and what pins are what.
Like this, but with YOUR particular ports and pin numbers that you are using:
Then it's just a matter of using the LCDOUT command...Code:DEFINE LCD_DREG PORTD 'Set LCD Data port DEFINE LCD_DBIT 4 'Set starting Data bit (0 or 4) if 4-bit bus DEFINE LCD_RSREG PORTE 'Set LCD Register Select port DEFINE LCD_RSBIT 0 'Set LCD Register Select bit DEFINE LCD_EREG PORTE 'Set LCD Enable port DEFINE LCD_EBIT 2 'Set LCD Enable bit DEFINE LCD_BITS 4 'Set LCD bus size (4 or 8 bits)
or if you wanted to display the content of a variable as a decimal number:Code:LCDOUT $fe, 2, "HELLO WORLD"
It's easy!Code:myvariable var word myvariable = 3955 LCDUT $fe, 2, DEC myvariable

Has anyone used this one? Is it any good?

Hi B_B
Ok, I'm sold
These LCD's look like great fun and a really useful interface.
When my first LED came on, that was brilliant. When my seven segment display /
driver lit up and counted up to nine that was cool.
These look in a different league, can't wait.

That one doesn't look like it's got a backlight. One with a backlight would be sexier...
Here in the US, I find these to be a good deal for $10USD.

Don't know about UK vendors.

Interrupt on change (interrupt when the state of a pin changes)
Again this is a snippet from another chip (16F873A) but it will give you something to start with.
Code:ON INTERRUPT GOTO MYINT INTCON = %10010000 'PORTB.0 CHANGE DISABLE MYINT: IF PORTB.0 = 1 THEN ' DO SOMETHING ELSE 'DO SOMETHING ELSE ENDIF INTCON.1 = 0 RESUME ENABLE 'THE ABOVE WILL ALSO DEBOUNCE THE SWITCH
